Caustic Soda Cost

Caustic Soda Cost

Caustic Soda Cost

(OP)
I have to balance the pH in a wet Scrubber to the tune of 7.0 to 7.5. The acid is coming from Sulfur in the air stream.  The caustic is costing me a furtune. about 1 mil per year.  Does anybody have any suggestions on how I can reduce this cost.

RE: Caustic Soda Cost

What is your cost/ton?  How quickly does it need to react?Some municipal wastwater plants use magnesium hydroxide for acid neutralization, but I don't think there would be much of a price difference and it needs time to react since it's insoluable.

RE: Caustic Soda Cost

Dear strebej,

First, let's take a few steps back.  What type of scrubber is being utilized?  What is the gas(or stream) you are scrubbing?

As soon as I have more details I may be able to point you in the right direction to dramatically reduce your caustic costs.  Also, where are you located?
